Application iiled September 17,1902. Serial No. 123.790. (No model.)

To all whom, t may concern,.-

Quincy, in the county of Adams and State of Illinois, have inventedcertain new and useful Improvemcn ts in Balig-Presses,'of which thefollowing is a full, clear, and exact description, reference being hadto the accom-v panyingdrawings, forming partof this speci# fication.

My present invention relates to thersame general character of abaling-press as those shown and described in my Patents Nos. 671,940,675,197, 678,941, and 682,240, issued,

respectively, on April 9, 1901, May 28, 1901,`

July 23, 1901, and September 10, 1901; and the objects of my presentimprovements are to provide for a quick preliminary forward movement ofthc traverser, also to provide an improved form of brake mechanism toretard the backward movement of the traverser,and also to provide asimple and effective mechanism for operating the feeder of the press.

My present invention consists in features .of novelty hereinafter fullydescribed, and" pointed out in the claims.

IFigure I is a detail top or plan view of the power end of my improvedpress, the sweep? shaft being shown in section. Fig. IIis a de-V tailelevation showing the power end of the press, the supporting axle orshaft being shown in section. Fig. III is an enlarged detail horizontalsection showing the brake mechanism, this section being taken on lineIII III, Fig. IV. Fig. IV is a vertical sectionof the brake mechanism,taken on line IV IV, Fig. I. Fig. V is a detail `side view, part vinsection, showing the upper end of the baling portion of the press. Fig.VI is a detail section taken on line VI VI, Fig. V. Fig. VII is a detailview of the feeder looking in t-he direction ofthe arrow, Fig. V.

Referring to the drawings, 1 represents the pitman of the press, havingan outervhead 2- and the inner end of'y which is connected to theplunger or traverser "of the press at 3, as shown by dotted lines inFig. V.

4 represents the' reach of V'the press, the' outer end of which connectswith'a'ca'sting or' bed-plate 5, supported by one of the wheelaXles 6 ofthe press, the other end of the reach Yfriction-rollers 13 at its ends.

lthe head -2.

ybeing made fast to the'baliug-chamber 7, as Be it known that I, WILLIAMR. COLMAN,` a citizen of the United States, residing inj shown at 8.

9 is the sweep-head of the press, made fast, as usual, to a verticalshaft 10,suitably mounted on the casting or bed-plate 5as, for instance,in, the manner shown and described in my Patent' No. 675,197, 11 in thisapplication indicating the frame orV yoke 9 of the patent lastmentioned. v 12 represents the cross-head of the press, .secured to theshaft 10 and provided with As in the patents referred to, the rollers 13move along the longitudinal face of the head 2 of the pitman Iuntil thelatter reaches a certain position in 4its forward movement, and then therollers come against the end of the head 2, forcing the pitman forwardto eect the final pressure on the plunger. One of the objects of mypresent invention is to obtain a long and quick preliminary forwardmovement of the pitman, and this I accomplish by connecting the innerends of the links 14 (which correspond to thelinks 13 of my Patent No.682,240) to a lever 15, tneouter ends of the links 14 being connected toa lateraliprojection 16 on The outer end'of the lever 15" Vhas a pivotalconnection with links 17 at 18, while the inner end of the lever isrounded .o to receivethe impact of the rollers 13 of the cross-head 12.

Y The inner ends of the links- 14 are pivoted dto the'lever 15 at 19,which is between the'inner end of the lever and the pivot 18l thereof.The outer ends of the links 17 are pivoted at 20 to the outer part ofthe yoke or frame 11. AsV the across-head 12 is turned'the nearestroller 13 comes against the lever 15, and by Jswinging the lever on its,pivot 18 and the links 1'7 on their pivot 2O the pitman is caused to bedrawn forward with a quick movement, the other -roller 13at this timebearing upon the'longitudinal inner face of the head2 of the pitman. Asthe ,pitma'n `reachesa certain position inits forward movement, which isnear the end of-its stroke, the groller13, which has been riding on thelongitudinal face of the head 2, passes around against theV end of 'thehead 2, as shown by dotted lines, Fig. I, andthe iinalpressure'on thepitman andplunger is exerted by a direct push of the cross-head againstthe end of the `pit'man. When the roller 13 leaves the head ICO of thepitman, the parts will rebound from the position shown by dotted linesin Fig. I to the position shown by full lines, in which position theyare ready to effect the next forward movement of the plunger as theroller 13 comes against the lever 15.

21 represents the carrier-arm of the press, which corresponds to thecarrier-arm 2O of my Patent No. 682,240. The pitman rests upon this armand causes it to be moved forward from the position shown in full lines,Fig. I, to the position shown in dotted lines as the plunger is advancedin the operation of the press. The carrier-arm is pivoted to the casting5, as shown in Fig. IV, the casting having a circular projection 22 toreceive a socket or hole formed in the carrier-arm, the arm being heldto the casting by means of a bolt 23 and a washer 24, the bolt passingthrough the washer and the casting or bedplate 5. The carrier-arm isthus free to revolve or turn on the projection 22. As stated, the arm ismoved forward by the forward movement of the pitman, owing to thefrictional contact between the two, and when the final pressure isexerted on the pitman and the cross-head leaves the head 2 of the pitmanthe latter rebounds, and the carrier-arm acts asa check to cushion therebound of the pitman, this action of the arm being effected throughmeans of a brake-shoe 25, pivoted at 26 to the carrier-arm and theconcave inner face of which bears against a fixed face 27 on the castingor bedplate 5. The shoe 25 is backed up by a coil-spring 23, located ina housing 29, formed on the under side of the carrier-arm, and back ofthe spring is a setscrew 30 for adjusting the tension of the spring sothat the pressure of the brake-shoe against the bed-plate 5 may beregulated as conditions may require. The outer end of the carrier-arm isprovided with a lug or ear 31, corresponding tc the lug or ear 23 of myPatent No. 678,941.

32 represents the feeder-arms of the press, used for the purpose offorcing the charges of material into the baling-chamber, these armsbeing secured to a rock-shaft 33, journaled iu boxes 34, secured to theupper face of the inner end of the baling-chamber, as shown in Fig. V..In order that the feederarms may be wholly outside of the hopper 35 ofthe press when the charges are being thrown into the hopper, I locatethe shaft 33 a short distance back of the hopper and form slots 36 inthe end of the hopper, through which the arms pass when they areoperating, these slots 36 being shown in Figs. VI and VII. To the end ofthe hopper 35 I secure brackets 37, which receive and. hold thefeeder-arms when in their upper positions and act to guide the arms tothe slots 36. The feeder-arms are moved from the position shown in fulllines, Fig. V, to the position shown in dotted lines by means of thesweephead, this being eifected by means of a crank 38, secured to oneend of the rock-shaft 33 and to which is connected one end of a cord orcable 39, that passes under a pulley 40, journaled to thebaling-chamber, the other end of the cable being connected to a lever41, that is pivoted at 42 to a block 43, made fast to the brace-rod 44of the press. The inner end of the lever 41 is curved, as shown at 45,Fig. I, and this end of the lever is in the path of projections(preferablyin the form of friction-rollers) 46, that depend from theunder side of the sweep-head 9. As the pitman advances and during thefirst part of its forward movement one of the projections 46 comesagainst the lever 45 and through means of the described connectionbetween this lever and the feeder-arms causes the latter to be moveddownwardly from the position shown in full lines inFig. V to theposition shown in dotted lines, thus causing the charge to be forcedfrom the hopper into the balingchamber of the press. When the sweep-headleaves the lever 45, the feeder-arms are returned to their normalpositions by means of a spring 47, connected at one end to thebaling-chamber of the press and at the other end to a crank-arm 48,secured to the rock-shaft 33. The cord or cable 39 is connected to thecrank 3S by means of a clevis 49, the bolt of which its `in a curvedslot 50, formed in the crank. The effect of `this is that during thefirst part of the movement of the feeder-arms ICO IOS

outer ends 5l are curved inwardly, the result l being that as thefeeder-arms move downwardly their main portions exert a downwardmovement on the material, while their outer ends tend to draw the chargeof material forwardly out of the hopper into the balingchamber.

It will be observed that the outer end of the pitman-head is formed onan incline and the outer corner of the head is provided with a friction-roller 60. By forming the outer end of the head with an inclination thecrosshead draws the pitmau inwardly as one of its rollers engages theouter end of the head of the pitman, and by providing the roller 60there is no danger of the end of the crosshead passing around the outercorner of the pitman head, for the roller 60 will come against theroller on the end of the crosshead and prevent any further lateralmovement of the end of the pitman after the roller 60 comes against theroller 13.
